All the fluff aside... The main problem I see throughout all of this - and something a lot of us deal(t) with - is that, you went in at full-speed, got too attached too soon, made it all about her, expected her to reciprocate everything you were doing (ie, you dont talk to any girls, only care about her, make her your world, and even TELL HER THIS).
This is all wrong. Now that you got these suspicions, you're too attached to leave. ALREADY. And just by wearing your heart on a sleeve like this - to where she knows she has you (since you keep TELLING HER OVER AND OVER) - she's almost bound to lose interest and leave... Sooner rather than later.
You put too much trust and faith AND your heart into someone you didnt even know. You dont give your heart out so easily, and you dont want to be thinking with your emotions this early. That just causes everything to go haywire in your mind. So, you end up viewing her as perfect and worthy - when reality is painting a different picture. These warning signs are the cracks of reality peeking out, and mustn't be avoided in favor of the fantasy, head in the clouds, infatuation **** going on in your mind. This causes major problems, gives away too much power, puts too much trust into someone who could very well use it against you, causes desperation, clinginess, and one-itis. All bad.
So now, since youre already attached and thinking only with your heart - red flags are excused, multiple chances are given, lies are omitted, everything can be worked out, serious conversations like you're married, she's a Godess, the "one", and worth the energy, anything for her. Blah blah.
You cant just "leave" - even when things go bad - and thats a problem.
Assuming this works out, or whatever... Dont do this again, or expect the same kind of overblown, obsessive, pushy behavior on your end. As well as your emotions being all over the place... pretty much running the show, women running for the hills, *****es taking advantage of you, etc. It'll definitely be a lesson learned, though.
Been all up in there before. The results are usually not pretty.
